# GMAT Arithmetic - Prep Course + Practice

Sometimes GMAT students just need to brush up on the basics. On the GMAT quantitative section, approximately 1/3 of the questions will involve arithmetic in some way. When we say “arithmetic” we’re not talking about 2 + 2 = 4. Rather, we’re talking about questions that either directly or indirectly test mathematical concepts ranging from fractions to weighted averages to statistics to prime factorization, and more. This complete GMAT Arithmetic Course covers all of the most important arithmetic concepts tested on the GMAT with tricks, shortcuts, and direct application questions to help you not only dust off those “math cobwebs,” but also get more right answers on test day.

"The Dominate the GMAT video lessons I used were a tremendous supplement to my GMAT prep and gave me a much better understanding of what the GMAT tests and the best strategies to beat it. Brett’s teaching style makes the material so easy to understand. I wish I had found these videos before I paid over \$1500 to another company!" -- Lauren White, USA
